I have installed the fancy plastic battery box liners and the group 26 12 volt battery will not fit, anybody know the correct battery that will fit in these battery box liners..?? I am doing a 72 to 67 conversion
Cheers

Take the battery box out, then it should fit.

I did like herb recommended. The box is on the driver's side for storage, battery is on passenger side in original frame. Perhaps you could take the box to the battery store and try to find a 12 volt that will fit.

A Westco AGM Miata battery will fit. It will be more expensive and have a lower CCA rating though. On the positive side, it will self-discharge at a much slower rate than a standard flooded lead acid battery, so the car can be left to sit for longer periods without starting.

I have a 67 with battery boxes and a Group 26 Battery I bought from Battery
Source. Its a very tight fit and is pretty much just wedged in there. I had to trim holes in the battery box for the cables but no other cutting. I suspect you may have one of those battery's with a protruding edge around the bottom. I understand they can be trimmed if necessary to make it fit.

Are there Autozone stores in Canada? Their economy model group 26 battery fits into the bin but it's still a tight fit. The Autozone mid-level and premium Group 26 batteries have that lip around the edge and they don't fit at all (without cutting).

Walmart johnson control. Group 26 fits the C&C box
Some group 26 need grinding off at the base to fit his case.

Some batteries have tabs on the bottom...these can be carefully trimmed off if that's what is impeding the battery's entry into the battery liner.

rather than a battery box, why not fabricate some sides/bottom and seal up the cradle? this will leave you with much more room.

I would rather have a fresh air for the battery to off gas into than a sealed box.

I did this conversion on a 1974. I had to use some 2*4's and wedge out the sides a bit, then the battery box will fit.

In my 1969 I am using an Interstate, Group 26 Megatron III, 665 cca. Nice snug fit. Only downside... it does not have the convenient lifting handle that some batteries have now..

Many thanks chaps for all your input, needless to say the consensus of opinion was to get rid of the liner and fit a Group 26 which is exactly what I have done, the left hand battery box with the liner is now a storage box!! I nearly bought the Mazda battery but at around $300 before taxes (that's Canadian) I gave it a pass..Cheers
